Before that, it's a bit murky in that I can say something that wasn't in this storefront, but not anything that was.

In 1998 (or perhaps late 1997) a party store was trying to locate here, but the liquor license application was contested. According to this SC Administrative Law Court Decision, the applicants apparently gave up on that idea before their appeal and rented the property to someone else. That "someone else" could plausibly have been Liberty, though no name is given.
